Why is APMs self-sealing washer an ideal solution for NEMA type 4X6 enclosure sealing?
To its advantage, the APM UL Recognized SEELOC® washer looks and performs differently than any other sealing washer. This compressible stainless steel washer, with a bonded silicone seal, features two concentric ridges that function as a barrier-rib – one on the outside edge and the other on inside hole surface making sealing contact with the mating screw/bolt shank creating a perfect high-pressure seal to 100 psi (internal/external).
